Abstract
Dyeing thermodynamics of cationic red 5GN on novel thermo-regulated polyacrylonitrile(PAN) fibers was studied and compared with common PAN fibers. The isotherm of thermo-regulated PAN fibers was similar to that of PAN fibers when dyed with cationic red 5GN at the same temperature, which was the Langmuir sorption. The partition coefficient, dye saturation value and dyeing affinity were increased with the rise of the dyeing temperature. The differences in the partition coefficient, dye saturation value and dyeing affinity at low temperature between thermo-regulated PAN fibers and PAN fibers were bigger than that at high temperature.关键词
